WWW EMA Patented Nov. 28, 1950 UNITED STATES PATENT OFFICE FISH TRAP WITH EXPANDIBLE HOOKS Mildred Ann Nolan, Coral Gables, Fla.
Application October 24, 1949, Serial No. 123,140
4 Glaims.
The present invention relates to the broad class of fishing and trapping and has more particular reference to that category which has to do with so-called trap hooks having a plurality of expandible impaling hooks and pull means for tripping and rendering said hooks operable.
As the opening statement of the invention implies, there are many and varied styles and forms of expandible and contractible trap hooks. Nevertheless, and notwithstanding, the still existing problem in this field of endeavor remains unsolved. Therefore, it is an object here to bring into being a, trap hook construction which is calculated to aptly meet the needs and requirements of manufacturers and users.
In reducing to practice a preferred embodiment of the invention, I have evolved and produced a selection and coordination of structural adaptations which combine in providing a fish trap in which users will find their needs and expectations fully met, contained and conveniently available.
Briefly summarized, a preferred embodiment of the invention has to do with an outer cylinder, an inner cylinder slidable within the confines of the outer cylinder and having coiled spring means associated therewith, spring opened and retained expandible hooks mounted on and carried by the inner cylinder, a spring held latch on the outer cylinder for setting and h'old- I ing the inner cylinder in readiness for activity, and a baited pull actuated hook for tripping said latch,
Novelty is predicated on the stated inner and outer cylinders and particularly, on the pivoted spring held expandible hooks and notches in the outer cylinder with which the shank portions of the hooks have fulcruming action in a manner to be hereinafter described.
Then, too, structural and functional novelty is thought to reside in the specific construction of the pull actuated bait hook, manner in which it is mounted and way in which it has trippable o'oaction with the spring returned and held latch.
Objects and advantages in addition to the above will, it is believed, become more readily apparent from the following description and the accompanying illustrative drawings.
In the accompanying sheet of drawings where in like numerals are employed to designate like parts throughout the views:
. Fig. l is a perspective view of atrap hook construction devised in accordance with the principles or the present invention;
Fig. 2 is a view with parts in elevation and section showing their construction and relationship at the time the trap is set and ready to be sprung by the victim, the section being on the plane of the line 22 in Fig. 4;
Fig. 3 is a sectional and elevational view based on Figs. 1 and 2 and showing primarily the relationship of parts at the time the trapis sprung; and,
Fig, 4 is a top plan view of the structure seen in Fig. 2.
The aforementioned outer cylinder is denoted by the numeral 6 and is substantially open at what may be designated as the lower end 8 and closed at the opposite end except for a stem accommodating and guide hole Ill. The open end or skirt portion of the cylinder is provided with circumferentially spaced notches l2 which serve a purpose to be later described. Then, too, the upper wall portion of the cylinder has a slot 14 to accommodate the detent end it of a latch or dog, the latter being pivoted between outstanding ears ll provided on the exterior of the cylinder. The latch, as best shown in Figs. 1, 2 and 3 has a curved tail-end l8 which constitutes what may be conveniently referred to as a trippable trigger. The numeral 20 designates spring means which is suitably mounted and associated with the latch for normally projecting the detent thereof through the opening M as brought out in Fig. 2, In addition, a component part of the cylinder takes the form of a cross-pin 22.
The inner cylinder 2d fits telescopically and slidably within the confines of the outer cylinder and said inner cylinder has its upper closed end provided with a stem or stud 26 projecting through and beyond the opening or hole E9 in the outer cylinder and terminating in a flat head or eye 28 to which the fishing line (not shown) is, in practice connected. The inner cylinder is adapted to shift back and forth in the outer one as shown in Figs. 2 and 3. In fact, the wall of the inner cylinder has diametrically opposite slots 30 which slide 011 the keying cross-pin 22. The expandible impaling hooks are carried by the inner cylinder and said hooks (there being at least three) are denoted by the numerals 32. The shank portions carry coiled springs 34 which are hingedly mounted in the skirt portion of the inner cylinder as at 36. The tendency or tension of the springs is to swing the impaling or trap hooks upwardly and outwardly to the open or expanded positions shown in Figs. 2 and 4. The spring hinged shank portions of hooks are arranged to operate in the stated fulcruniing notches 12. The main trap spring ,isdcnoted by the numeral 38 and is a suitably tensioned coil. spring and this is confined in the inner cylinder and bears at one end against the cross-pin 22 and at the opposite end against the closed end of the inner cylinder. In Fig. 2 the spring 38 is shown compressed or set and. in Fig. 3 it is shown expanded, which is the position when the trap has been sprung.
The pull actuated means comprises a bait hook 40 having a shank; 4'2 which is polygonal in cross section and which is slidable, but not turnabie in guides 4d and 46 mounted on the exterior of the outer cylinder 6. The guides have leg portions 38 and 5%! whereby they may be conveniently fixed to said outer cylinder. One end of the shank is formed into a hook 52 and the hook eon-- stitutes a trip and is releasably engageable, with the aforementioned trigger iii. ihe sliding stroke of the shank ea in the stated guides is limited by a suitable shoulder or stop element 54 mounted on said shank and shiitable back and forth between the two guides at and 16,.
It will be evident that when the inner cylinder is in the out position shown in Fig. 2 and the spring is compressed, the latch or dog it will engage with said inner cylinder, the trigger 88 will move out and the trip 52 may then be engaged with the trigger as shown in Fig. 2. It will also be clear from Fig. 2 that when the trap is set,
the respective impaling or trapping hooks 32 under action of the outswinging springs 3:? swing outwardly to open or expanded positions. Assuining that the trip hook at has been suitably baited, it will be obvious that when the expected relative pull is exerted on the bait carried by said hook, the trip will serve to depress the trigger i8 and this will release the latch it against the tension of spring 2d. Spring 38, being then free, will expand and force the inner cylinder 24 into the outer cylinder 6 as shown in Figure 3. As the pivoted ends of the shanks of the impaling hooks ride into cylinder t and the shanks rock and cam against the crotch pcrtions of the notches l2, it is obvious that said hooks 32 will be rocked into contracted or grappling positions. Consequently, the victim will be securely snared by and held in the spring actuated trap hooks,
It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of e invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
Minor changes in the shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice if desired.
